Nitish Kumar, who arrived in the national capital on Saturday noon, met Gandhi at his residence 12, Tughlaq Lane in central Delhi in the evening.

The close door meeting between the two leaders lasted for over 40 minutes.

What transpired was not officially communicated but sources in the Congress said the two leaders discussed the current political situation in Bihar following the CBI raids against RJD Chief Lalu Prasad's family.

Nitish Kumar's meeting with Gandhi comes days after Congress President Sonia Gandhi spoke to the Bihar Chief Minister and RJD chief Lalu Prasad in an effort to prevent a collapse of the Grand Alliance.

The meeting took place amid speculation that Nitish Kumar, who is JD-U President, was growing closer to the BJP.

The Janata Dal-United (JD-U), Congress and Rashtriya Janata Dal (RJD) are partners of Bihar's ruling Grand Alliance, which is in the throes of a political crisis due to the CBI raids on RJD leader Tejashwi Yadav's premises over an alleged benami land deal.
The JD-U, in its efforts to portray a corruption-free image, has demanded that Tejashwi Yadav quit, which has been rejected by the RJD and the Congress.

Talks between Nitish Kumar and Tejashwi Yadav last week do not seem to have smoothed the political ripples.

The party sources said the two leaders also discussed about how to keep together the opposition parties in view of future politics.
